Saliva hormone testing is most useful for uncovering hormone imbalance. For example: discovering a woman has insufficient progesterone to balance high estradiol levels or; that high cortisol levels are interfering with the action of progesterone and testosterone. Once a hormone imbalance has been uncovered, homeopathic treatment can be instituted.
Saliva testing can be used to approximate whether hormone levels are too high or too low as a result of supplementation, but the actual dosage adjustment will still be symptom driven.
Saliva collection is painless and more convenient for the patient, particularly when multiple samples are required.
Saliva measures hormone that actually made it into tissue, because hormones pass through saliva gland tissue before getting into saliva. Blood measures hormones that might eventually get to the tissue.
